Sjávarmælir GT23M-TM - afturborðsplata CHIRP/ClearVü

The Garmin GT23M-TM is a plastic transducer designed for transom mounting. It integrates traditional mid-band CHIRP sonar and CHIRP ClearVü technologies. This 8-pin model provides a versatile solution for detailed underwater detection, with depth tracking and water temperature capabilities.

The Garmin GT23M-TM fishfinder is specifically designed for inshore and offshore anglers, providing detailed underwater detection for these environments.

The traditional CHIRP sonar of the Garmin GT23M-TM sounder operates on a mid-band frequency range of 80 to 160 kHz.

The Garmin GT23M-TM sounder's traditional CHIRP sonar has a power output of 600 W.

The Garmin GT23M-TM traditional CHIRP sonar can reach a maximum depth of 549 meters (1,800 feet).

The CHIRP ClearVü sonar of the Garmin GT23M-TM sounder operates on frequencies of 260/455 kHz, specifically 245-275 kHz and 445-465 kHz.

The CHIRP ClearVü sonar of the Garmin GT23M-TM transducer has a power output of 500 W.

The Garmin GT23M-TM transducer with CHIRP ClearVü sonar can reach a maximum depth of 305 meters (1,000 feet).

The beam angle of the traditional CHIRP sonar in the Garmin GT23M-TM fishfinder ranges from 24° to 13°.

Yes, the Garmin GT23M-TM transducer can track water temperature.

The Garmin GT23M-TM transducer cable is 9.1 meters (30 feet) long.

To install the GT23M-TM transducer, you will need the following tools:

A drill and drill bits (a 4 mm (5/32 in) bit for pilot holes and a 25 mm (1 in) bit for the 8-pin cable pass-through)Two 13 mm hex keysA #2 Phillips screwdriverMasking tapeMarine sealant

For optimal performance, the depth sounder should be mounted:

As close as possible to the centerline of the boat.In an area of clean water (non-turbulent), away from propellers, chines, reinforcements, fittings, water discharge outlets, or anything that could create air bubbles.At least 38 cm (15 inches) from the propeller and on the opposite side of the propeller’s rotation to avoid prop wash.So that the center of the bottom of the transducer is level with the bottom edge of the transom and parallel to the waterline.

To reduce interference with the sonar signal, it is recommended to:

Mount the transducer away from sources of electromagnetic interference (electronic devices, engines, radar). Avoid turbulence zones created by hull features (steps, chines, ribs) or the propeller. Install the transducer away from sources of acoustic noise (other transducers, boat machinery, wind, waves, rain). If the transducer cable must cross a power cable, route the cables at 90 degrees to each other. If using multiple transducers, mount them at least 60 cm (24 inches) apart if they operate on the same frequency.

The GT23M-TM transducer, being a transom-mounted model, is not recommended for:

Sailboats, due to excessive roll.Multi-chine hulls.

After installation, test the transducer in open water:

Turn on the chartplotter with the boat in the water. Drive the boat at low speed, then gradually increase speed while monitoring the chartplotter. If the sonar signal is lost or severely degraded, note the speed at which this occurs. Return to the speed where the signal was lost and make moderate turns in both directions while monitoring the chartplotter. If signal strength improves when turning, adjust the transducer to extend 3 mm (1/8 in) lower below the transom. Repeat steps 2 to 4 until degradation is eliminated. If the signal does not improve, move the transducer to another location on the transom and repeat the test.

The Garmin GT23M-TM transducer, being a transom-mounted transducer, is compatible with all hull materials.

Yes, you can run multiple depth sounders simultaneously. If you use two sounders with the same frequency, they must be mounted at least 60 cm (24 inches) apart to avoid interference. Two sounders with different frequencies can operate simultaneously without this distance restriction.

Yes, the Garmin GT23M-TM transducer is suitable for towable boats. It is designed for easy installation and removal. However, it is vulnerable to external damage from trailers or underwater obstacles.

Yes, it is important to note that cutting cables connected to the depth sounder will void your warranty.
